BLOUNTVILLE, TN (WJHL) A former priest from Kingsport convicted of sexually abusing a child in his congregation three decades ago lost his latest legal fight Friday.

William Casey was in Sullivan County Criminal Court trying to convince a judge to force the District Attorney General’s Office to recuse itself from his case.

A judge denied that request Friday.

Four years ago, a jury convicted Casey of rape and sexual misconduct involving a child over the period of 5 years during his time as priest at St. Dominic’s Catholic Church in Kingsport.

Casey is serving a 35 to 40 year prison sentence.

A judge previously denied Casey’s request for a new trial and a separate request that Judge James Goodwin remove himself from the case.

A “post conviction” hearing was set for February 3rd when it’s expected Casey’s attorney will argue he had ineffective legal representation during the trial.Copyright 2015 WJHL. All rights reserved.
